Peak expiratory flow7/8/2023 ![]() ![]() To further characterize obstructive and restrictive lung diseases.Assess lung diffusion capacity (by measuring DL CO).↓ FVC and ↓ TLC: restrictive lung disease.↓ TLC: mixed obstructive and restrictive lung disease (e.g., COPD plus obesity, or silicosis).Normal or ↑ TLC: obstructive lung disease.Assess lung volumes (on spirometry and/or body plethysmography): to determine the main pattern of disease.Volume of air that remains in the lungs after the exhalation of a normal TV Maximum volume of air that can be exhaled after the inspiration of a normal TV Maximum volume of air that can still be forcibly exhaled after the exhalation of a normal TV Maximum volume of air that can be inhaled after the exhalation of a normal TV Maximum volume of air that can still be forcibly inhaled following the inhalation of a normal TV Volume of air that is inhaled and exhaled in a normal breath at rest Volume of air that remains in the lungs after maximal exhalation 1992 29:283-6.Volume of air in the lungs after maximal inhalationĭifference in lung volume between maximal exhalation and maximal inhalation Peak expiratory flow rates of healthy tribal children living at high attitudes in the Himalayas.

A study of peak expiratory flow rate in normal healthy children of Punjab. ![]() Boys have more PEFR values than girls across all age groups. The correlation is more robust with regard to height. ![]() The co-efficient of regression derived for height was found to be highly statistically significant both in boys and girls.Ĭonclusions: Significant correlations were found between PEFR and biological variables like age, weight, height and chest circumference. Among all the study variables, height had shown the maximum positive correlation to PEFR in both boys and girls. Results: PEFR values were measured in a large number of children between 6 and 12 years and varied significantly between boys and girls in the age group 6 to 12 years. Methods: The study was conducted from February 2005-August 2006 among healthy children between 6 and 12 years of age attending urban schools of both sexes in Chennai. Here authors planned to measure PEFR in healthy school going children between 6 and 12 years and correlate PEFR against various parameters such as height, weight, sex, age and chest circumference. Bronchial asthma is among the commonest disorders in childhood. Peak expiratory flow rate, School going children, Urban schools in Chennai Abstractīackground: Peak expiratory flow rate (PEFR) is an important tool in monitoring patient’s changes in asthma.
